ZendDebugger Remote Debugging

I am trying to set up remote debugging from our web server.  Due to the firewall in place here, I had to set up an ssh tunnel back to my local machine.  When I establish a debugging connection, the debugger panel shows Connected, but the code doesn't seem to run, and ebven though I have break at first line selected, no break point is triggered.  I have triple checked all of the configuration settings on both the server and in Phpstorm.  Anyone have any ideas on what I might be missing?

Thanks
